Bulgy Eye Surgery - Orbital Decompression VS. Orbital Expansion: What's the difference between these two procedures?




What is bulgy eye surgery? What's different about our bulgy eye surgery? In order to understand what makes EFIL unique, a basic understanding of what bulging eyes are.

Orbital bone is the bone that makes up what is commonly referred to as the eye socket. When the eye socket is shallow, usually a result of congenital factors, due to the lack of sufficient space the eyeball can be forced outward, slightly protruding. This eye protrusion is called many things: bulgy eyes, exophthalmos, proptosis, among others.

Shallow orbits (shallow eye sockets) are not the only cause of eye protrusion. Eye protrusion can also be an indirect result of thyroid disorder.

When problems occur in the thyroid glands, orbital tissue swelling is common. The thyroid glands produce more thyroid hormone than is necessary leading to a condition called thyrotoxicosis. One of the symptoms of thyrotoxicosis is the swelling of tissue in the orbit, pushing the eyes outwards and making the eyes protrude.


Eye protrusion due to congenitally shallow orbits tend to cause relatively mild functional and cosmetic problems. When eye protrusion is a result of thyrotoxicosis, the consequences may be more severe. Swelling behind the eye can cause intraocular pressure (pressure behind the eye) to increase. This not only forces the outwards, but can cause functional problems and negatively affect vision. In extreme cases, high intraocular pressure can damage the optic nerve and cause blindness.

High intraocular pressure can be dangerous. Orbital decompression surgery is one surgical option for dealing with it.  Orbital bone is shaved down, or sometimes broken and cut out, and orbital tissue is removed. This creates space in the orbit in turn lowering intraocular pressure.

The main objective is the lowering of the dangerously high intraocular pressure. For this reason, orbital decompression surgery has been considered an "emergency" operative procedure. As orbital bone is broken, there tends to be a lot of bleeding, and the procedure itself is known to take between 5-6 hours. Because of its invasive nature, unlike other eye surgeries, a week-long stay in the hospital is not unheard of.

When intraocular pressure is not a factor, and the procedure is purely aesthetic, expansion of the space in the orbital room becomes the main purpose. The ethmoid bone (the bone that separates the sinus and the brain) may be convex in shape, and the actual orbital room may be shallow. When this is the case, bone is not cut out, it is cut and simply pushed in. Orbital tissue is likewise removed. Since the tissue is not swollen, the procedure is safer as there are less risk factors, less bleeding and less invasiveness. Since there is less to remove, the procedure is much shorter when compared to orbital decompression, and recovery time is faster.

To sum up the difference between two procedures, orbital decompression surgery is an invasive surgical procedure with the aim of cutting away at orbital bone and swollen orbital tissue for the purpose of lowering dangerously high intraocular pressure.

Orbital expansion surgery removes orbital tissue and pushes orbital bone inwards to expand the orbital room and make room for the eye to be set more appropriately in the eye and improve aesthetic proportion in the face.
